Is this my Thomson router giving weird figures or is there a problem? The router is plugged into the main socket.
Thanks for any info.

Maybe a Plusnet DC team member could have a look at your connection history as well.

I would say that's the start of an intermittent connection issue that's slowed since the lowering of the profile. Probably worth running through the wizard at http://faults.plus.net and our faults agents will get it sorted for you.

Normally connection seems to drop for about a minute every 4 - 5 days. However recently it has been reconnecting at a lower speed which has been cured by going into the router and disconnecting and reconnecting once but the SN margin has been staying at 3. Just over a month ago on the 10th April I had a few disconnections in quick succession and the SN margin rose and the slower speed stayed for about a week. Hope it is not an intermittent fault as they never happen when you want them to. Will raise a fault on Monday if more connection drops.
Thinking back I had a phone call last night about 9-00 and there was noise on the line but I know the caller has had problems so thought it was his line. Phone seems fine now and I've tried a quiet line test with a corded phone which was OK.

Remember copper is sensitive to electromagnetic interference, don't run it near power or anything of that sort. Make sure your wiring is not loose in your socket.

not lost connection overnight so if (as seems likely) it is an intermittent fault and happens again I will go through the faults wizard suggested by Matt. I guess that if the line remains stable then the SN margin will drop and the speed increase.
This morning the router stats show -

Easiest thing to do is contact your phone line service provider, get them to check the line for noise. If it requires an engineer to visit after testing, that's what needs to be done... I can see that the line isn't in a perfect state so just get in touch and they should be able to help you out.
